I hope they carry the same tone from these trailers/teasers over into the actual stories. It's been too long since we had a proper serious/dark Dalek story, and it looks like we might just get it! So excited!

Poop on the Daleks, I'd be happy with the Dr. verses Davros with a couple of Dalek slaves thrown in... Big finish have done an amazing job utilizing the evilness and pure genius that is Davros with out having Daleks in every scene... check out "The Juggernauts" and "Davros". It is a shame we dont get the quality of the Big Finish production and scrips on the TV episodes but oh well....

Fold's historically suffix definition is "of many parts". Capaldi is the Twelfth incarnation of the man who identifies as the Doctor, the fourteenth regeneration of said individual.

Everlasting Death for the most faithful companion...

Assumed to be talking about Donna at the time, but consider...Clara scattered herself across the Doctor's time stream, fated to die again and again, all to help save the Doctor from the machinations of the Great Intelligence.

Well, the Cult of Skaro were meant to be the unorthodox thinkers of the Dalek Empire (Pre-Time War Dalek Empire, I should amend). What if Caan wasn't insane...but playing a longer game?

When you think of the Daleks we have now - the Parliament, New Paradigm, maintainers of an asylum, their Puppets...it's a vastly different Dalek organization then we had in the Classic series. And the New Paradigm was created using pure DNA samples of Daleks/Kaleds. No half-breed mutant offshoots like the Emperor's brood or even Davros' (As Davros was a mutant even by the standards of his own people).

Once Davros' own "Children" abandoned him, it's possible Caan revealed what he'd learned - Gallifrey was not destroyed, as we ourselves learned in the 50th.

Jaw Drops*

Guys. Davros was going to detonate a reality bomb. Pete's World got involved because while they weren't directly threatened, the stars were going out which tipped them off something was up. Gallifrey was shunted into a pocket dimension hidden somewhere in reality.

Of course, that would never have been RTD's reasoning for these things, but it certainly adds a new dimension and depth to The Stolen Earth/Journey's End. I like it. It's also a lot better than Davros just being like, "Yeah I made all of these Daleks and I'm gonna blow up reality just for the sake of it." I hope Moffat makes this canon.
